For the attached AOI, the land use (GLCLU) breakdown for 2020 is as follows:

• Tree cover: 47.58% (236709.61 hectares)
• Dense short vegetation: 27.71% (137882.35 hectares)
• Ocean: 14.85% (73926.31 hectares)
• Open surface water: 9.44% (46995.14 hectares)
• Built-up: 0.16% (778.65 hectares)
• Cropland: 0.23% (1160.77 hectares)
• Sparse vegetation: 0.03% (140.35 hectares)
• Salt pan: 0.003% (12.75 hectares)

The total area of the AOI is 497,724.77 hectares.

Combining the "Tree cover" and "Dense short vegetation" classes for the attached AOI:

• Combined percentage: 47.58% + 27.71% = 75.29%
• Combined hectares: 236,709.61 hectares + 137,882.35 hectares = 374,591.96 hectares
